Here's how to lock and put any Android device to sleep with a double tap (no root required!)

Here's how to lock and put any Android device to sleep with a double tap (no root required!)
While the likes of the various double-tap-to-wake and double-tap-to-sleep gestures that can be found in a large number of smartphones are, all in all, yesterday's news, there is still a whole cornucopia of devices that are devoid of these features.

What a pity! Although some may argue that these are not handy at all and add nothing positive to the user experience interface, we can't deny that these can potentially be among the show-stopping features of your brand new smartphone - after all, the iPhones can't do that just yet.

But what if your manufacturer has decided that the users of its brand new product deserve no such thing, be it double tap to wake the device or put it to sleep? Well, you have several options before you. The more advanced requires you to search high and low for a custom kernel for your rooted device that supports said gesture features and flash it. Although you'd be safe if you follow the instructions, there's always a pretty big risk that something will go wrong. Are you willing to take the chance?

Well, there are much easier ways to implement one of the aforementioned gesture features, which is completely safe, requires no rooted device, and, as an added bonus, will even save you some battery juice!

Got your attention? Here follows the guide you've been looking for!

No, this is strictly a launcher feature. You'll probably need a custom kernel to do what you described.

This is why I love Android. All these possibilities are all amazing. Makes customization a true awesome feature to Android!

Yes, but you need a phone with an AMOLED screen

1. AMOLED/OLED screen. 2. Battery drain more than normal. If you fine with both, head to Play Store and look for Knockr If no, no. Or get an LG

Just search for screen off on the play store and there you have it

Great, but... When I double-tap the screen, it does lock the phone, but turns it on immediately. Any help?

Would you go to Greenify's settings and share what's enabled and what not exactly?

instead of greenify, use a app that locks the screen instead? Plenty of such app if u search lockscreen in playstore.
